   ECMA Section:       11.3.1 Postfix increment operator
   Description:
   The production MemberExpression : MemberExpression ++ is evaluated as
   follows:

   1.  Evaluate MemberExpression.
   2.  Call GetValue(Result(1)).
   3.  Call ToNumber(Result(2)).
   4.  Add the value 1 to Result(3), using the same rules as for the +
   operator (section 0).
   5.  Call PutValue(Result(1), Result(4)).
   6.  Return Result(3).
